Upper Kuparuk River Region SPOT NDVI
The French SPOT satellite data (20-m resolution) were obtained on 28 July 1989 and provides a view of the mapped region from space. NDVI is an index of vegetation greenness that... -
Upper Kuparuk River Region NDVI trend 1985-2007 (Raynolds et al 2010)
Landsat TM and ETM data were used to calculate NDVI for the study area (823 km^2). This image shows the results of a slope of linear regression of NDVI for 1985, 1989, 1995,... -
Ivotuk Vegetation Maps (Reidel et al. 2005)
The Ivotuk study site is located in northwestern Alaska, on the North Slope of the Brooks Mountains Range. The study site was chosen because four tundra vegetation types, moist... -
West Dock Patterned-Ground 10 x 10 m Grids
The West Dock biocomplexity grid is located near the water pumping facility at West Dock in the Prudhoe Bay oilfield, AK, within 1 km of the Beaufort Sea coast. There is one 10... -

The Deadhorse patterned-ground grid is located near the industrial center of Deadhorse, AK, within 15 km of the Beaufort Sea coast. There is one 10 x 10 m grid, with a complex... -
Howe Island Patterned-Ground 10 x 10 m Grids
The Howe Island biocomplexity grid is located on a 1.5 x 0.5 km island off the delta of the Sagavanirktok River, west of the Endicott Causeway in the Prudhoe Bay oilfield, AK.... -
Happy Valley Patterned-Ground 10 x 10 m Grids
The Happy Valley patterned-ground grids are located in Subzone E, the warmest part of the Arctic, in the foothills of the Brooks Range, just west of the Sagavanirktok River and... -
Circumpolar Arctic AVHRR False Color-Infrared (CIR) Map
Advanced Very High Resolution Radiometer (AVHRR) data were obtained from the USGS Global AVHRR 10-day composite data. (http://edcdaac.usgs.gov/1KM/1kmhomepage.asp) (Markon et... -
Sagwon Patterned-Ground 10 x 10 m Grids
The Sagwon patterned-ground grids are located at the northern edge of the rolling foothills, at the boundary with the flatter coastal plain. This is also the boundary between... -
Alaska Arctic AVHRR NDVI Map
The normalized difference vegetation index (NDVI) is a measure of greenness. NDVI was calculated as: NDVI = (NIR - R) / (NIR + R), where NIR is the spectral reflectance in the... -
Franklin Bluffs Patterned-Ground 10 x 10 m Grids
The Franklin Bluffs patterned-ground grids are located in Subzone D, on the coastal plain of the Alaska North Slope, just west of the Sagavanirktok River. There are three 10 x... -
Circumpolar Arctic Biomass (Raynolds et al 2012)
This map portrays an estimate of above ground plant biomass for the tundra biome based on trans-Arctic field data and AVHRR NDVI (Raynolds et al. 2012). Aboveground phytomass... -
